The Utility of “Google Trends” for Epidemiological Research: Lyme Disease as an Example

Geospatial Health, Volume 4, Number 2, May 2010, Pages 135-137

Ari Seifter1, Alison Schwarzwalder2, Kate Geis3, John Aucott4

“Internet search engines have become an increasingly popular resource for accessing health-related information. The key words used as well as the number and geographic location of searches can provide trend data, as have recently been made available by Google Trends. We report briefly on exploring this resource using Lyme disease as an example because it has well-described seasonal and geographic patterns. We found that search traffic for the string “Lyme disease” reflected increased likelihood of exposure during spring and summer months; conversely, the string “cough” had higher relative traffic during winter months. The cities and states with the highest amount of search traffic for “Lyme disease” overlapped considerably with those where Lyme is known to be endemic. Despite limitations to over-interpretation, we found Google Trends to approximate certain trends previously identified in the epidemiology of Lyme disease. The generation of this type of data may have valuable future implications in aiding surveillance of a broad range of diseases.”

Evaluating a 50 Year Record of Forest Encroachment in Rocky Mountain Alpine Meadows

95th Ecological Society of America (ESA) Annual Meeting, Pittsburgh, PA, 01-06 August 2010

Sunita Yadav and Stephen F. Matter

“The potential impact of global warming is predicted to be strongest at higher altitude and latitude. Alpine meadows are already limited in their spatial extent and are especially vulnerable to rising temperatures which may cause them to retract substantially or completely disappear due to invasion by woody forest species. It is generally believed, that during periods of warmer than average temperatures, tree-line increases in altitude. In our study, we analyzed the record from 1952 to 2009 of forest encroachment in the Alberta Rocky Mountains. We quantified the extent of meadow areas along two ridges in the front ranges of the Canadian Rockies to explore land cover change. Historical aerial photographs, image processing, and geographic information systems (GIS) tools were used to quantify the extent of forest encroachment over the past 50 years. Using an orthorectified base map, we co-registered the aerial photographs and classified forest and meadow areas. Actual areal extent was calculated in a GIS program.  The results clearly show a significant decrease in meadow area with the majority of the reduction occurring within the past two decades. The consequences of such dramatic landscape change have cascading effects on meadow populations leading to reduced overall species diversity and smaller individual species populations due to fragmentation and isolation. Further work on this system involves studying the effects of this fragmentation on the population structure of a Sedum species occurring in these meadows.”

2010 Exemplary Systems in Government (ESIG) Winners Announced

URISA’s Exemplary Systems in Government (ESIG) Awards recognize exceptional achievements in the application of information technology that have improved the delivery and quality of government services. URISA is pleased to announce the winners of this year’s ESIG Awards.

ENTERPRISE SYSTEMS CATEGORY

Systems in this category are outstanding and working examples of using information systems technology in a multi-department environment as part of an integrated process. These systems exemplify effective use of technology yielding widespread improvements in the process(es) and/or service(s) involved and/or cost savings to the organization.

2010 ESIG Winner:

  • OneMap – A Multi-Agency Window for Geospatial Information and Service Delivery – Singapore Land Authority
    Submitted by: Lim Ming Khai, Head, GeoSpatial Operations & Development, GeoSpatial Division, Singapore Land Authority

One of the core functions of the Singapore Land Authority (SLA) is to promote and proliferate the sharing and use of geospatial data among government agencies so as to support better decision making and the creation of new business opportunities. OneMap is a common map platform for public agencies to publish information and deliver map-based e-services to the public. OneMap is also available to businesses, who can leverage a free API to create useful and value-added location-based services that will benefit the public.

The motivating factor for this system was not to create a web mapping application for any specific department or agency, but the desire to create a common platform that could then be used by ANY department or agency to display their geospatial data. This is a country wide initiative with very granular local data. System development relied on multi-agency collaboration and effective use of agency resources. A unique aspect of the system is its inclusion of non-government partners and the provision of APIs to allow the public to not just consume the data, but to allow private enterprise to use the system as a platform for creating their own web map applications by using their own data and allowing these to be embedded in non-SLA websites. It is a major step forward for any national government to try and share non-sensitive data with its citizens.  It is another major step to develop systems that can be freely consumed by private and public agencies to provide value added service delivery.

Distinguished System in this Category:

  • City IQ – City of Bellingham, WA
    Submitted by: Don Burdick, GIS & Technical Services Manager, City of Bellingham, WA

SINGLE PROCESS SYSTEMS CATEGORY

Systems in this category are outstanding and working examples of applying information system technology to automate a specific SINGLE process or operation involving one department or sub-unit of an agency. The system application results in extended and/or improved government services that are more efficient and/or save money.

2010 ESIG Winner:

  • Situational Awareness for Field Operations Support System – New York City Office of Emergency Management
    Submitted by: Hassan Adekoya, GISP, GIS Application Development Project Manager, NYC Office of Emergency Management

The primary objective of the NYC Office of Emergency Management (OEM) is to plan and prepare the city for emergencies, coordinate emergency response and recovery, and educate the public in order to better prepare for emergencies. The Situational Awareness for Field Response System (SAFRS) was developed to assist the agency’s Operations Division in acquiring immediate situational awareness as an incident is reported as well as to provide citywide tracking on all OEM monitored incidents. The system allows watch commanders and citywide interagency coordinators/field responders to access and query the agency’s GIS data sets from their desks or vehicles. In addition, SAFRS integrates with other systems to provide more comprehensive information to first responders; these system integrations did not require modifications to existing workflows.

The system is unique in being able to both create a spatial “dashboard” map of situations on the go, and being able to output a package of materials for use by field personnel. An important impact was the dramatic reduction in time required to produce situational awareness materials – from a former response time of 60 minutes to a current response time of 60 seconds – critical in the time-sensitive domain of emergency response. This system’s human resource efficiencies are also commendable.  The entire project was designed and developed using only in-house staff, and following launch, the need for after-hours GIS staff was eliminated, saving $174k/yr.

Distinguished System in this Category:

  • Pierce County GIS Online Budget System – County of Pierce, WA
    Submitted by: Art Seeley, GISP, Interim GIS Manager, County of Pierce

Ability to Detect and Locate Gross Errors on DEM Matching Algorithm

International Journal of Digital Earth, Volume 3, Issue 1 March 2010 , pages 72 – 82

T. Zhang; M. Cen; Z. Ren; R. Yang; Y. Feng; and J. Zhu

“Digital elevation model (DEM) matching techniques have been extended to DEM deformation detection by substituting a robust estimator for the least squares estimator, in which terrain changes are treated as gross errors. However, all existing methods only emphasise their deformation detecting ability, and neglect another important aspect: only when the gross error can be detected and located, can this system be useful. This paper employs the gross error judgement matrix as a tool to make an in-depth analysis of this problem. The theoretical analyses and experimental results show that observations in the DEM matching algorithm in real applications have the ability to detect and locate gross errors. Therefore, treating the terrain changes as gross errors is theoretically feasible, allowing real DEM deformations to be detected by employing a surface matching technique.”

Stan Meiburg to Discuss Challenges in Using GIS for Environmental Protection at GIS-Pro 2010

URISA is pleased to announce Stan Meiburg as the opening keynote speaker at GIS-Pro 2010 in Orlando. Stan Meiburg is the Acting Regional Administrator for the U.S. Environmental Protection Agency Region 4 in Atlanta, Georgia. In his keynote address, “From Environmental Information to Environmental Action: Challenges in Using GIS for Environmental Protection,” Mr. Meiburg will discuss the barriers to the use of GIS applications in setting environmental policy and producing environmental improvement. These barriers include integrating technical tools, data quality, laws and regulations, unclear policy objectives, and political will.  They can be overcome with patient, persistent, professional leadership and collaborative efforts, but they pose significant challenges which go beyond simply refining GIS applications.

Danielle Ayan, GISP, GIS-Pro 2010 Conference Chair offers that “U.S. EPA Region 4 has experienced tremendous activity over the past several years, including the Gulf of Mexico Oil Spill and other pollution challenges, mountaintop mining, climate change and green living, to name a few. While these activities are not necessarily unique to EPA Region 4, it is impressive how EPA Region 4, under Mr. Meiburg’s direction, is leveraging the geospatial approach for managing and addressing them.”

Mr. Meiburg will deliver his keynote address on Wednesday, September 29, 2010 at GIS-Pro 2010: URISA’s 48th Annual Conference for GIS Professionals in Orlando. For more information, visit www.gis-pro.org.
